test buildout: use solrinstance recipe 3.6 instead of checkout, fixes 'ValueError: zero length field name in format'
'Topic' is now 'Collection'
removed testNoIndexingWithMethodOverride as ATPortalTypeCriterion is now obsolete and there seems to be no other example of an object that does not want to be indexed
'Topic' is now 'Collection', round 2
removed testReindexSkipsNonReferencableItems, see a24b3b4ccef74e1e55811db517d8d277316badd7
CatalogTool.indexes is not patched any more, adapted test
'Topic' is now 'Collection', round 3
fixed setQuery for Collection test. Test still fails, but this now reveals an actual problem, as the error also happens on a real site with plone.app.collection and collective.solr installed
